History of the Centennial Kumquat

It is believed that the Centennial kumquat is a result of a spontaneous mutation founded by HC Barette in 1986. This mutation occurred at the Whitmore Foundation Farm in Leesburg, Florida, where they planted and grew the Nagami kumquat. It is believed that one of these Nagami trees was pollinated by an unknown source that, in turn, created the Centennial kumquat, talk about a happy mistake.

Characteristics of the Centennial Kumquat


This small upright growing tree produces a shrubby appearance with waxy green and yellow leaves. The Centennial kumquat flowers tiny white flowers before the production of the immature fruits, which are small, dark, and light green striped.

As the fruit matures, it turns into a bright orange oval that stands out against the dark green and yellow leaves. Once fully mature, you can expect the Centennial kumquat tree to reach anywhere from four to eleven feet in height and three to four feet in diameter.


Centennial kumquats have slightly acidic, very sweet, juicy flesh, and a thinner outer peel. The longer the fruit matures, the sweeter this kumquat variety becomes.

Growing the Centennial Kumquat

Planting Zones

The Centennial kumquat can grow either in pots or straight in the ground as long as you plant them in the USDA Hardiness zones eight to eleven. These trees can be grown indoors and outdoors or even sat on a patio or porch in the summertime and moved inside if you have more harsh winters.

Soil and Sunlight

These kumquat trees prefer coarse well-drained soil if planting them into the ground, and if potting, pick a course, acidic and well-drained soil.

As far as sunlight, these trees can take half of the days worth of full sun, so part sun, part shade, would work wonderfully. If you plan to place these trees in pots and have them indoors, ensure they stay near a nice sunny window.


The Centennial kumquat is self-pollinating, which means they do not need any other pollinators around to help in the production of fruits. If you want to give them a helping hand, take a small paint brush and dust the pollen from flower to flower.

Bloom Time and Bearing Age

You can expect to see these trees in full bloom mid-spring with their petit white flowers covering most of the branches.

Kumquat Plants Growing

Unfortunately, you won’t see any fruit being produced until the tree is at least two years old and has been established for about one to two years.

Watering and Fertilizing

The Centennial kumquats prefer wet, well-drained soil, so there is no need to over-water these trees, but if trying to establish, make sure the soil keeps a slight moisture level at all times.

Fertilize three times a year using citrus tree fertilizers. The best times to do so are late winter, spring, and early fall.

Pests and Diseases

Even when planted outdoors, these kumquat trees are rarely affected by any type of pests. One thing you may need to keep your eyes open for is slugs.

If planted indoors, aphids and mites may find their way onto your plants but can be eradicated with simple measures.

Diseases on these plants are also uncommon. Making this one easy to care for kumquat trees.


Once you have a well-established tree that begins to bear delicious kumquats, you can expect to harvest late fall to early winter. Some harvests may even bring you up to thirty pounds of fruit. You better remember to jot those recipes down.
